What to do if you ever want to create a story
Write. At least a word everyday. And try to never skip a day.
It doesn't have to be great. That's not your goal. Just try to add new words to your drafts each day. Just put your ideas out there.
You don't have to worry about grammar. Don't try to make it good. Don't even think about your readers. You can do all of that when rereading your drafts.
If it's weird you can change it later. So write. If it's wrong you can correct it afterward. So don't even check. If it's horrible you can simply delete it. So don't be ashamed.
Just let your thoughts out. Try all of your ideas. It's easier to sort them when it's on paper. So put everything on paper.
It's useless to ask for directions if you never plan to walk. So start to walk now. Check sometimes along the way to see if it's the correct road. Maybe you'll have to go back, or take a different route. You can't guess what road you'll take. But one day you will make it to your destination.
So don't think about what you will write. Just write. Or else you will never achieve your goal. Or else you will never write your story.
